$conn is defined as a global in a file called database.inc which is
here:

<?php
//
// database.inc
//
// Database Information

$dbname = "personnel";
$dbuser = "webuser";

$conn = pg_pconnect("dbname=$dbname user=$dbuser");
if (!$conn) {
echo "Could not connect to database.";
exit;
}
?>

As you can see, I'm using pg_pconnect.
